Meeting on Product Plan Optimization and Feasibility Study Review for Yueneng Group’s 400,000 tons/year coal-based arylene olefin co-production project Held/Source: Yihua Coal Chemicals Date: 2019-06-10 Clicks: 27 On June 5, a meeting on product plan optimization and feasibility study review for Yueneng Group’s 400,000 tons/year coal-based arylene olefin co-production project was held in Tianjin. The meeting was chaired by Huang Ye, the deputy chief engineer of the group, with participation from units such as the Shaanxi Provincial Development and Reform Commission, the Yulin Municipal Development and Reform Commission, the Yushen Industrial Zone Management Committee, the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, Sinopec Luoyang Engineering Co., Ltd., and China Tianchen Engineering Co., Ltd. The conference invited 8 industry experts and scholars, including He Yongde, Li Chen, and Li Xingang, to serve as reviewers. The experts present listened to an explanation of the DMTA technology provided by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, as well as a joint presentation by the organizations responsible for preparing the feasibility study report (Sinopec Luoyang Engineering Co., Ltd. and China Tianchen Engineering Co., Ltd.) on aspects such as the product design, process flow, overall layout, environmental protection measures, investment estimates, and technical-economic analysis related to this project. Through thorough discussions, valuable suggestions were put forward regarding the project’s product technical solutions and feasibility report, laying a solid foundation for the subsequent progress of the project. Departments such as the Planning and Development Department, Engineering Management Department, Safety and Environmental Protection Department, and Financial Assets Department of the group company attended the meeting. Yulin City is advancing three processes for the production of coal-based aromatics. It is reported that Yulin Energy Group’s 500,000 tons per year coal tar deep processing and multi-product production project utilizes a fluidized-bed technology developed by the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences, which is used to produce p-xylene along with olefins from methanol and toluene (DMTA). Construction of this project is expected to be completed this year, after which it will become the first and largest coal-based aromatics production facility in China. The total investment in the project is 4 billion yuan, with an expected annual profit of 500 million yuan after it goes into operation. It is reported that Yanchang Petroleum Group has 6 subsidiaries, including Yulin Kaiyue Coal Chemical Company, Anyuan Chemical Company, and Yuheng Coal Chemical Company. The developer of the Yuheng coal-based aromatics project is Yanchang Petroleum Yuheng Coal Chemical Company. According to Hou Qinli, the company’s chairman and general manager, the project utilizes the world’s first fluidized-bed methanol-to-aromatics (FMTA) technology developed by Tsinghua University. It is planned to be built in the Yuheng Industrial Zone and consists of an industrial demonstration project for coal-based aromatics as well as a coal-based aromatics production facility. The investment in the industrial demonstration project amounts to 7.378 billion yuan; the main product is 325,800 tons per year of mixed aromatics, while by-products include 25,200 tons per year of LNG and 38,300 tons per year of ethane. After the project is put into operation, it can achieve an annual total profit of 560 million yuan. The total investment in the coal-based aromatics project is 42.69 billion yuan, which will further facilitate complementarity among aromatic compounds. The first phase involves an investment of around 16.7 billion yuan, intended for the construction of facilities for producing 1.8 million tons per year of methanol from coal, 600,000 tons per year of MTO, 200,000 tons per year of light hydrocarbons, 400,000 tons per year of polyethylene, and 350,000 tons per year of polypropylene. The second phase requires an investment of around 25.99 billion yuan; it builds upon the existing aromatic compounds production capabilities by expanding into the polyester industry, with facilities for producing 1.8 million tons per year of methanol from coal, 600,000 tons per year of MTA, 700,000 tons per year of combined aromatic compounds, 1.1 million tons per year of PTA, 450,000 tons per year of ethylene glycol from coal, and 1.3 million tons per year of PET. The project has now been approved by the Shaanxi Provincial Development and Reform Commission; upon commissioning, it is expected to generate an annual profit of 6.4 billion yuan. Together with the demonstration project for the selective utilization of coal to produce new chemical materials, carried out by Shaanxi Coal and Chemical Industry Group and utilizing its own independently developed technology for the rapid pyrolysis of low-grade coal dust, all three processes for producing aromatic compounds from coal are now available in Yulin City.
